प्रश्न
Write the equation for the action of heat on:
(i) Ammonium chloride
(ii) Ammonium nitrate
State whether each reaction is an example of thermal dissociation or thermal decomposition.
उत्तर
(i) Action of heat on ammonium chloride is reversible. When heated, it decomposes to form ammonia and hydrogen chloride. When the products are cooled, they recombine to form ammonium chloride .
